Achieving Low-latency Handoff through Two-Stage Authentication in WLAN

IEEE 802.11 WLANs are widely deployed nowadays. While a mobile device is moving around it may need to execute a handoff that usually requires authentication. This results in a long processing delay and leads to degradation of quality of service to the mobile device. Existing authentication methods such as AAA and IEEE 802.1x mechanisms are unable to accommodate low-latency handoff. In this arti...

Achieving High-Latency, Low-Bandwidth Communication: Logic Emulation Interfaces

There is a large amount of interest in using multi-FPGA systems for logic emulation and rapid-prototyping of digital systems. One difficulty with this approach is the handling of the external interfaces of the system. In this paper we describe a generic interface transducer, a board capable of handling the external interfaces of the system under prototype, allowing the emulation to operate in t...

Avoiding Implementational Heat Achieving High Performance with Fpga-based Computing

Lawrence Snyder stated the three basic parameters for the MPP portability problem.3 First, a parallel solution using P processors can improve the best sequential solution by a factor of P, at most. Second, HPC problems tend to have thirdor fourth-order complexity, and so parallel computation, while essential, offers only modest benefits. Third, “the whole force of parallelism must be transferre...

Analysis of Latency Performance of Bluetooth Low Energy (BLE) Networks

Bluetooth Low Energy (BLE) is a short-range wireless communication technology aiming at low-cost and low-power communication. The performance evaluation of classical Bluetooth device discovery have been intensively studied using analytical modeling and simulative methods, but these techniques are not applicable to BLE, since BLE has a fundamental change in the design of the discovery mechanism,...
